The Bosco Verticale / Vertical Forest high-rise complex in Milan, Italy. The plant life, which is said to equal 3 hectares of forests (20,000 sq m), not only moderates the temperature in summer and winter but also converts as much as 30 tonnes of CO2 each year. On top of that, it filters out dust particles, protects the residents from noise pollution and creates a microhabitat for insects and birds.
